The Littelfuse 0437007.WR is a 7A fast-acting surface mount fuse from the 437 series. It is designed for overcurrent protection in high ambient temperature environments, operating from -55°C to 150°C. The fuse is housed in a compact 1206 (3216 Metric) package measuring 3.20mm x 1.63mm x 0.82mm, suitable for automated assembly.
Electrically, the fuse is rated at 7A continuous current with a maximum voltage of 32V AC and 35V DC. It has a breaking capacity of 50A at rated voltage and a fast blow response time. The nominal melting I²t is 5.02 A²s, providing high inrush current withstand capability. Other electrical characteristics include a DC resistance of 0.01Ω, a voltage drop of 0.13V at rated current, and power dissipation of 0.91W.
This fuse is environmentally compliant: RoHS3, lead-free, and halogen-free. It holds CSA and UR agency approvals, meeting UL/CSA/NMX 248-1 and 248-14 standards. The 0437007.WR is suitable for leaded and lead-free reflow/wave soldering processes.
Typical applications include power supply protection, board-level overcurrent protection in consumer electronics, industrial controls, and any circuit requiring reliable fast-acting protection in a small surface mount footprint.
